Notes

The storage carbohydrate granules from Euglena and Pavlova were compared by light and electron microscopy. Freezeetch studies demonstrated that while both types of granules are crystalline, they have different structures. The elemental microfibril of the euglenoid granule measures 4 nm, and the elemental striation of the granule from Pavlova is 22 nm. The granules each have a unique X-ray diffraction pattern. The storage carbohydrate granules from Pavlova are not the same as paramylon, and the term "paramylon" should be reserved for the euglenoid storage carbohydrate.
